In order to determine the effective cross-section properties, it is necessary to define at least one load case (Table 2.1 Load Cases) with the corresponding internal forces (Table 3.1 Internal Forces): the effective cross-section properties are load-dependent.
Furthermore, c/t parts (Table 1.7 c /t Parts) are required for the calculation. Usually, they are created automatically by the program.

In SHAPE-THIN 8, the effective cross-section of stiffened buckling panels can be calculated according to EN 1993-1-5, Cl. 4.5.
The critical buckling stress is calculated according to EN 1993-1-5, Annex A.1 for buckling panels with at least 3 longitudinal stiffeners, or according to EN 1993-1-5, Annex A.2 for buckling panels with one or two stiffeners in the compression zone. The design for torsional buckling safety is also performed.
The material database in RFEM, RSTAB and SHAPE-THIN contains steels according to the Australian standard AS/NZS 4600:2005.
EN 1993-1-3
EN 1999-1-1 
to DIN 18800-2
EN 1993-1-1
EN 1999-1-1 
All results can be evaluated and visualized in an appealing numerical and graphical form. Selection functions facilitate the targeted evaluation.
The printout report corresponds to the high standards of RFEM and rstab/rstab-9/what-is-rstab RSTAB. Modifications are updated automatically.
